Supersonic retropropulsion (SRP) has not yet been utilized for planetary Entry, Descent and Landing (EDL) although its use has been theorized since the 60s. EDL trajectories with SRP enable landing larger masses on Mars than those possible using aero

The remains of a saltworks, in operation from c. 1550-c. 1650, were investigated at Port Eynon, near Swansea, in response to the threat of marine erosion. The site is an early example of salt production by the open-pan method. In the 17th century, a

The Mars Science Laboratory (MSL) Mission will land a 900-kg rover on the surface of Mars in 2010. Four Mars Lander Engines (MLE's) will be fired during the final propulsive descent to maintain a 0.75 m/s vertical rate of descent, in support of a tet
